Per-country analysis with exponential and sigmoidal projections, and new cases analysis

IMPORTANT: The projections are only accurate if the fit is good (it often isn't), and assuming nothing changes going forward. The sigmoid is omitted if a reasonable fit can't be computed, but this still doesn't mean that the fit is good if it is shown.

The dashed lines show best fit projections from a few previous days for comparison.
